JavaScript Arrays

• Arrays are fairly similar to objects, they have different stored values and syntax, but can be used for almost anything.

• Here is the same code as objects but in an array:

var choosePill = ['Red', 'Blue', 2];

var choice = choosePill[0];

console.log(choice); // Outputs 'Red'

Reminder: Most programming languages start from 0, not 1, so when we access the choosePill variable, we grab the value from the 1st position.

• Arrays are extremely important when storing multiple values within a variable.
• This way we don't have to write 100 variables and instead can store them all in a single variable, this is an array.
• There are multiple ways to write an array, but this one is simplest and most basic version is the example above.
